WebJun 21, 2016 · 7. We were asked the reaction between 1 mole acetone and 1 mole B r X 2 in basic medium. Since only a limited amount of bromine was given I got the final answer as 1-bromopropan-2-one (mono bromo acetone). However, in the given solution the entire haloform reaction was shown with C H B r X 3 and acetate ion as the final product. WebMay 12, 2014 · Now bromine is known to be easily polarised X δ + X 2 2 δ + B r − B r X δ − and may intercept at any point of the ring causing a bond break and relaxation to a less strained structure.
